It is divided into 32 sectors.

On the other hand, 23 is a keymate for inputting a unique search code and various operation commands corresponding to image information. Reference numeral 24 denotes an output device such as a cathode ray tube display device (hereinafter referred to as a CRT display device) serving as a display section, which displays image information or an optical disk read by a two-dimensional scanning device R20 and supplied via the main controller 1. The main controller 11 displays image information read out from the device 22 and supplied via the main controller 11.
The display interface 12 and the display interface 12 constitute a significant image information display device. 25 is a recording device;
Image information read by the two-dimensional scanning device 20 and supplied via the main controller 11, or image information read from the optical r4 scan device 22 and supplied via the main controller 11, etc. 26. Reference numeral 27 denotes a magnetic disk device, and an optical disk 19 stores the search code inputted through the keyboard 23, the size of image information corresponding to the search code, and the image information.
Search data consisting of the above memory address is transferred to magnetic disk 2.
8, one piece of image information is stored.

As shown in FIG. 3, the search data is composed of a search code storage area that stores a 54-byte search code divided into six items at most, and a storage address storage area that stores storage addresses.

This storage address storage area has the number of image storage sectors L1.
Track number T-AD as image information start address
R sector pick-up S/ADH.

The image size S is stored.

The empty area of the storage area of image size S is a deletion prohibited code storage area (deletion prohibited data storage area) a where a deletion prohibited code (deletion prohibited data) is stored, and a deletion code storage area b where a deletion code is stored. and is provided.

Next, the operation in such a configuration will be explained. No trenches,
Registration (storage) of image information will be explained with reference to the flowchart shown in FIG. For example, now, the key date 23 is selected and set to the registration mode, and a search code for image information to be registered is entered. As a result, the CPU 12 checks the validity of the input data (cyclic redundancy check, CRC check) according to the predefined search code format based on the number of digits, character type, etc., and also checks the already registered search code. If the search code is overwhelming as a result of these checks, it is stored in the main memory 13. Next, the CPU 12 displays the search code on the CRT 7-'4 display device 24, and also displays a message asking, ``Do you want to issue a command to prohibit deletion?''. When deletion prohibition is specified according to this guidance, the deletion prohibition code is stored in the main memory 13 in association with the search code. Then, the original is set on the two-dimensional scanning device 20, and the CP
U 12 is an optical disk device 22 and a two-dimensional scanning device 2
Operate 0. The two-dimensional scanning device 20 two-dimensionally scans image information such as a set document and performs photoelectric conversion. This photoelectrically converted line information is stored in the page buffer 14.
are stored sequentially. When one page's worth of image information is stored in the page buffer 14, the image information is stored in a fresh memory (not shown) within the display interface 17, and the image information is displayed on the CRT display device 24. By the way, if the image displayed on the CRT7'' display device 24 is satisfactory, a registration key (not shown) is input.Then, the CPU
12, a compression/decompression circuit 15 compresses each unit of line information, which is one unit of image information stored in the page buffer 14, by the well-known Mu (Modify-Hoffman) conversion, and compresses the compressed line information. The data is supplied to the optical disk device 22. Accordingly, the optical disk device 22 stores the supplied image information on the optical disk 19.

When the storage of this image information is completed, the CPU 12' stores in the main memory 13 storage addresses such as the track number where the image information is stored, the start limit, and the length of the image in correspondence with the search code.

Next, the CPU 12 supplies the search code, deletion prohibition code, and storage address stored in the main memory 13 to the magnetic disk device 22. Thereby, the magnetic disk device 27 stores the supplied search data on the magnetic disk 28.

In addition, if deletion prohibition is not designated when the deletion prohibition designation is announced, the image information of the document is stored in the optical disk 19, and the search r-data consisting of this storage address and the search code is stored in the magnetic disk 28. be done.

Thereafter, other image information is stored on the optical disk 19 in the same manner.

Next, a search for image information registered as described above will be explained. First, the key 23 is set to the search mode and the search code is input. Then, the CPU J 2 transfers the search code to the magnetic disk 28.
The search code is sequentially compared and checked with the search code stored in the , that is, the search code of the magnetic disk 28 corresponding to the currently set optical disk 19 is sequentially compared and checked to see if the search code matches the input search code. Check sequentially. CPU J 2 for matching search code
reads the sector number, track number, and starting sector number of the image at the storage address. And CPU 12
causes the optical disc device 22 to reproduce the track on the optical disc 19 corresponding to the track number. Then,
CPU 1 j! supplies the image information (compressed information) from the optical disk device 22 to the compression/expansion circuit 15 for each scanning line, performs band expansion by M)I inverse conversion, and sequentially supplies the original image information to the page buffer 14. . When all the image information for the reproduced page is stored in the page buffer 14 in this way, the CPU 12 displays the image information on the CRT display device 24 using the fresh memory (not shown) in the display interface 16. , or make a hard copy using the recording device 25.

Next, deletion of the image information registered as described above will be explained with reference to the flowchart shown in FIG. First, the keyboard 23 is set to delete mode and a search code for deletion is entered. Then,
The CPU 12 compares the search code with the search code stored on the magnetic disk 28, and sequentially checks whether or not the search code matches the input search code. The CPU 12 causes the CRT fIsgray device 24 to display the matching search code for one or the number of boards. Based on this display, the operator selects and inputs the number of the search code to be deleted using the keyboard 23. Accordingly, the CPU J 2 checks whether or not a deletion prohibition code is stored in the deletion prohibition code storage area a corresponding to the search code, and if it is stored, determines that deletion is prohibited and performs the deletion process. Terminate the process without performing any operations. Also,
If the deletion prohibition code is not stored, the CPU 12 determines that deletion is possible, reads the storage address, number of image storage sectors, track number, sector number, and image size of the selected examination code from the magnetic disk 28, and deletes the selected examination code from the magnetic disk 28. The optical disc device 22 is caused to reproduce the track on the optical disc 19 corresponding to the number. Then,
The CPU 12 supplies the image information (compressed information) from the optical disk device 22 to the compression/expansion circuit 15 for each scanning line, performs band expansion by MIH□ inverse conversion, and sequentially supplies the original image information to the page buffer 14. do. When all the reproduced image information corresponding to one negative value is stored in the page buffer 14 in this way, the CPU 12 causes the image information to be displayed on the CRT display device 24 using the display interface 16. The operator confirms this display and, if the image is to be deleted, presses a deletion key (not shown). When this deletion key is input, CPU12
By storing the deletion code in the deletion code storage area b of the corresponding search code in the magnetic 7" disk 28,
Perform deletion processing. As a result, the image information corresponding to the search data in which the deletion code was stored is deleted.

Next, the cancellation of the inhibition of deletion of the image information registered as described above will be explained with reference to the flowchart shown in FIG. 6. First, when the key is pressed to the key 23, the mode is set to the deletion prohibition release mode, and a search code for canceling the deletion inhibition is input. Then, the CPU 12 sequentially compares the search code with the search codes stored on the magnetic disk 28, and sequentially checks whether the search code matches the input search code.

CPU 12 causes matching search code or codes to be displayed on CRT display device 24. Based on this display, the operator selects and inputs the number of the search code for which deletion inhibition is to be canceled into the key date 23. Accordingly, the CPU 12 checks whether or not a deletion prohibition code is stored in the deletion prohibition code storage area a corresponding to the search code, and if it is not stored, determines that deletion is possible, and cancels the deletion prohibition. Terminates processing without performing any processing.

In addition, if a deletion prohibition code is stored, CPU1
2 determines that deletion is prohibited, reads the storage address of the selected search code, the number of tb image storage sectors, the track number, the sector number, and the image size from the magnetic disk 28, and deletes the track on the optical disk 19 corresponding to the track number. is played back by the optical disc device R22. Then, the CPU 12 supplies the image information (compressed information) from the optical disk device 22 to the compression/expansion circuit 15 for each scanning line, performs band expansion by MH inverse conversion, and sequentially transfers the original image information to the page buffer 14. supply In this way, when all the image information for one reproduced page is stored in the page buffer 14, the CPU 12 displays the image information on the CRT display device 24 using the display interface 16.
display it on top. The operator confirms this display and, if the image is to be deleted, inputs a deletion prohibition release key (not shown). When this deletion prohibition release key is inserted, CPU J 2 becomes magnetic! 4 school 2
By deleting the deletion code in the deletion code storage area b of the corresponding search code in 8, the wide deletion prohibition cancellation process is performed. As a result, the image information corresponding to the search data in which the deletion code was stored can be deleted.
